An airway device comprises an airway tube 1, foam cuffs 3,4, and a gastric channel 2. One end of the airway tube has a silicon seal 1 at one end, and a connector 7 at the other for connection to the breathing system (not shown). Surrounding the airway tube and the gastric tube are two cuffs 3, 4. One cuff 3 is made from closed cell foam, which may be compressed for insertion into the throat; it then expands to seal the throat. The other cuff 4 is made from open cell foam, which absorbs fluids to prevent inhalation. The cuff removes the need for a secondary throat pack. |
